Original Mopar NOS Oil pressure sending unit for 1989 and up 2.2 Turbo cars that have both an oil pressure gauge as well as a low oil light.   Will also fit some late build 88 2.2 Turbo cars as well.  This sensor is "w/gauge".  Mopar part number:  4687814
 
Note:  This unit has TWO pins on it.  This means it will operate both your low oil pressure *light* on your cluster as well as your oil pressure *gauge*.  This is important.   Bottom line, if you have a Shelby/Dodge or Chrysler TC by Maserati you want this sensor.
